There's at least one member of Sen. Rand Paul's family who isn't quite on board just yet with a 2016 run - and that's his wife.

After a speech at the Detroit Economic Club today, Paul, a Republican senator from Kentucky, was asked whether he plans to run in 2016, and he revealed his wife's displeasure with the idea of a run for the White House.

"Where's my cellphone? Can I call my wife?" Paul joked. "There's two votes in my family. My wife has both of them, and both of them are 'no' votes right now.

"If I'm a very able politician, I'll tell you in a year whether I'm able to persuade my wife. Right now, I don't know yet, but I thank you for your interest," he added.
